Bob's Plumbing charges $50 for a house call

Mathematics
1 answer:
viva [34]3 years ago
8 0

Answer:

C(8) = $290

Step-by-step explanation:

Since Bob's Plumbing charge a flat fee of $50, then it is the y-intercept.

As detailed in the given problem, x is the number of hours they work.  

They charge $30 for every x number of hours on the job. This represents the slope.

C(x) represents the total cost of working for x number of hours.

Given these factors, we can establish the following function rule:

C(x) = 30x + 50

To evaluate the function for 8 hours of work:

C(8) = 30(8) + 50

C(8) = 240 + 50

C(8) = 290

Therefore, the cost of working for 8 hours is $290.

What is the quotient? Negative StartFraction 3 over 8 EndFraction divided by negative one-fourth
anyanavicka [17]

Answer:

\dfrac{3}{2}

Step-by-step explanation:

We are given 2 fractions.

1st fraction is Negative StartFraction 3 over 8

i.e.

-\dfrac{3}{8}

2nd fraction is negative one-fourth

i.e.

-\dfrac{1}{4}

We have to find the quotient when 1st fraction is divided by 2nd fraction.

<u>Definition</u> of quotient is given as:

Quotient is the result obtained when one number is divided by other number.

-\dfrac{3}{8} \div -\dfrac{1}{4} \text{ is to be calculated.}

\div is converted to \times and the 2nd fraction is reversed i.e.

if the fraction is \frac{p}{q} it becomes \frac{q}{p} and the sign \div is changed to \times.

Solving above:

-\dfrac{3}{8} \times -\dfrac{4}{1}\\ \text {Multiplication/Division of 2 negative number gives a positive number}\\\Rightarrow \dfrac{3}{2}

So, the quotient is \frac{3}{2}.
